Description

一种沙漠绿化的方法 技术领域
本发明涉及环保技术领域，尤其涉及一种沙漠绿化的方法。
背景技术
荒漠化(desertification)是由于大风吹蚀，流水侵蚀，土壤盐渍化等造成的土壤生产力下降或丧失；1992年世界环境与发展大会上通过的定义是“包括气候和人类活动在内种种因素造成的干旱、半干旱和亚湿润地区的土地退化”。据联合国环境规划署(UNEP)统计，全球已经受到和预计会受到荒漠化影响的地区占全球土地面积的35％；其中非洲占55％，北美和中美占19％，南美占10％，亚洲占34％，澳大利亚占75％，欧洲占2％。世界平均每年约有6-10万平方公里土地荒漠化；半个世纪以来，非洲撒哈拉沙漠南部荒漠化土地扩大了65万平方公里。全世界陆地面积为1.62亿平方千米，占地球总面积的30.3％，而沙漠面积已占陆地总面积的10％，还有43％的土地正面临着沙漠化的威胁。1953年，Peveril Meigs把地球上的干燥地区分为三类：
特干地区是完全没有植物的地带(年降水量100mm以下，全年无降雨、降雨无周期性)，其面积占全球陆地的4.2％；
干燥地区是指季节性地长草但不生长树木的地带(蒸发量比降水量大，年降水量在250mm以下)，其面积占全球陆地的14.6％；
半干地区有250-500毫米雨水，是可生长草和低矮树木的地带。
荒漠化存在着逆转和自我恢复的可能性，这种可能性的大小及荒漠化逆转时间进程的长短受不同的自然条件(特别是水分条件)、地表情况和人为活动强度的影响。只有在沙漠地区供应充足的淡水，才可以实现沙漠的恢复，但现有技术还没有利用人工供应淡水的方法实现沙漠绿化的完善方案。
发明内容
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供一种沙漠绿化的方法，以解决现有技术的不足。
为实现上述目的，本发明提供了一种沙漠绿化的方法，其特征在于，包括以下步骤：
步骤1，挖填充槽，在充槽表面铺设阻水防渗层；
步骤2，在阻水防渗层上再铺设沙层，在沙层上再铺设植物生长层；
步骤3，在植物生长层上再铺设草编网格，将卷扬机上的草垫连接到山地车的挂钩上，山地车启动，向前开动，保持匀速运行，直到将卷扬机上的草垫全部铺垫完毕；
步骤4，在草编网格中撒上植物种子，然后喷水。
上述的一种沙漠绿化的方法，其特征在于，所述铺设的草编网格采用植物编制的草垫制成，将若干个草垫用草绳连接起来，形成几百米长的草编网格。
上述的一种沙漠绿化的方法，其特征在于，所述的草垫用可降解的秸秆和无纺布构成，上下两层构成，在一定间隔设置了作物植物种子室，植物种子室有空穴，使种子从空穴中生长，使植物根须深入沙层，叶子伸出草垫。
上述的一种沙漠绿化的方法，其特征在于：所述草垫卷在卷扬机的转轴上，每个草垫的规格是等距的10米、20米、1米、2米宽。
本发明的有益效果是：
本发明的方法来绿化沙漠，可以将有条件的、可以绿化的沙漠绿化，应用区域广泛，便于规范化施工，提高沙漠植被覆盖率，可以改善沙漠局部的生态环境。
以下将结合附图对本发明的构思、具体结构及产生的技术效果作进一步说明，以充分地了解本发明的目的、特征和效果。
附图说明
图1是本发明的实施例结构示意图。
图2是本发明的草垫结构示意图。
具体实施方式
如图1所示，一种沙漠绿化的方法，其特征在于，包括以下步骤：
步骤1，挖填充槽，在充槽表面铺设阻水防渗层；
步骤2，在阻水防渗层上再铺设沙层，在沙层上再铺设植物生长层；
步骤3，在植物生长层上再铺设草编网格，将卷扬机1上的草垫2连接到山地车4的挂钩3上，山地车4启动，向前开动，保持匀速运行，直到将卷扬机1上的草垫全部铺垫完毕；
步骤4，在草编网格中撒上植物种子，然后喷水。
本实施例中，所述铺设的草编网格采用植物编制的草垫2制成，将若干个草垫2用草绳连接起来，形成几百米长的草编网格。
如图2所示，本实施例中，所述的草垫2用可降解的秸秆和无纺布构成，上下两层构成，在一定间隔设置了作物植物种子室21，植物种子室21有空穴，使种子从空穴中生长，使植物根须深入沙层，叶子伸出草垫2。
本实施例中，所述草垫2卷在卷扬机1的转轴上，每个草垫2的规格是等距的10米、20米、1米、2米宽。
本发明由于沙层中设置了阻水防渗层，阻水防渗层阻止了水的流向，水再不会往沙层深处到处乱渗漏，从而达到节约用水的目的。使用的材料均是绿色环保，不会污染人和自然环境。由于合理的供水，可均匀的供给绿化所用的植物，植物可以快速成长，有效解决绿化沙漠用水和雨水防渗问题。用该方法来绿化沙漠可以将有条件的、可以绿化的沙漠绿化，应用区域广泛，便于规范化施工，提高沙漠植被覆盖率，可以改善沙漠局部的生态环境。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思做出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
